Special Instruction Under Installation
1. Reserve enough space for stretching.
The stretching degree effected by temperature of cast acrylic sheet is as followed.
After finishing processed acrylic novelties at 10°C, when temperature raised to 50°C, the heat expansion will be 1000*8*10¯5*(50-10)=3.2m/m.
After finishing processed acrylic novelties at 30°C, when temperature falls to -10°C, the contraction will be 1000*6*10¯5*(30+10)=2.4m/m.
General settlements to prevent from troubles:
Reserve the frame for contractility
Making the screw hole in oval
Cushion material should as elastic as rubber
Forming acrylic sheet into not significant shape
Using straighten or forming way to increase the cross-sectional coefficient to avoid interior stress
2. Prevent Transformation:
Forming acrylic sheets into wave , wrap and through to increase cross-sectional coefficient in order to prevent transformation from the weight of acrylic sheet itself and loading. Increasing thickness of acrylic sheet when length and the dimension is larger. It necessary to calculate thickness related to tension tolerance and ending strength of acrylic sheet on the surface that endures wind pressure.
